Managed IT Services Handle Incident Response
The SANS Institute defines an incident response process in Computer Security Incident Handling: Step-by-Step, and this model is what most MSPs use to deliver Services managed it incident response services. A good MSSP will help you map and prepare for an IR plan, rehearse it to ensure your team is ready in the event of a breach and offer support throughout a security incident.
The first part of the IR process, identification, involves monitoring systems and networks for anomalous activity. Security tools like firewalls, antivirus and intrusion detection systems, and endpoint protection platforms can detect and alert on suspicious behaviors that may indicate an attack is underway. The next phase, resolution, requires your team to follow a logical sequence of steps that reduces risk and business impact. This includes shutting down a compromised system, restoring from reliable backups, and testing and repairing systems to make sure no traces of the threat remain.
To prevent slow responses, teams should have a well-mapped IR plan in place that is rehearsed regularly and is designed for different scenarios. This will also help them to identify the right resources for each scenario and ensure that non-technical teams, such as legal and communications, are involved in case a breach occurs.
Once an incident is identified, teams must prioritize and classify tickets to address them quickly. Using a ticketing system with predefined templates for different incident types makes it easier to categorize incidents correctly and resolve them faster. For example, a service desk may offer different tiers of support for password resets or more complicated problems.
How Managed IT Services Handle Incident Response
During the containment stage, your team will implement short- and long-term containment strategies, such as isolating affected systems and blocking malicious traffic and access attempts. Your MSSP will likely be able to implement some of these containment tactics remotely, depending on the type of services they provide for you.
Once the eradication and recovery phases are complete, your teams can restore all systems and devices to their pre-attack state. This typically involves removing malware, closing vulnerabilities and security gaps, resetting passwords and revoking compromised credentials, and rebuilding the system from clean backups. It can take time to recover from a data breach, but an experienced and knowledgeable MSSP can speed up the process with automated patching and vulnerability management tools.
An effective MSSP will also maintain configuration backups for their Services managed it, IDS, AV and content scanning systems to help you return to normal operations after an incident. They will also perform a post-mortem review of the incident and its impact to help improve future security events by learning from your experience. This information can be used to create and update policies, automate routine tasks, and improve machine learning and AI-enabled tools to identify incidents more quickly.
Cloud computing has revolutionized how businesses store and access data. Managed IT services include cloud-based solutions that enable businesses to access scalable, flexible, and secure IT resources without the need for expensive on-premise infrastructure. Cloud Storage: Businesses can store data on remote servers, reducing the need for physical storage devices and ensuring accessibility from any location.
